Fastest routing algorithm?
 
What is the fastest routing algorithm used by most of the protocols.

Thank You
Greg

It really depends. Are you talking internally or externally. It also depends on the size and scope of the network.

OSPF or IS-IS are the most common internal routing protocols (IGP, interior gateway protocols) for the major backbone networks.

OSPF is the most common, but IS-IS is gaining in popularity.
EIGRP is really not that great IMHO

..not to mention that EIGRP, for the most part, is cisco proprietary.

i know ospf converges faster than rip, but also floods the entire network

Flood is a relative term. OSPF does a good job of controlling the spread of that information. Multi-area OSPF design permits you to define boundries for summarization to prevent the spread of unnecessary information. If the network is designed properly the "flooding" wont be a major issue.

Thanks for this valuable definition.

i dont have much knowledge of this but i have heard a lot about ospf algorithm.although i dont know that how it works but i think that it is the fastest one.

ospf is good but in the case where an entire network is running OSPF, and one link within it is "bouncing" every few seconds, OSPF updates would dominate the network by informing every other router every time the link changed state.

OSPF is normally used for most routing processes, Don't know much about others.
